This is how netezza and teradata do it and it works very well.
In each of their cases you can see a graphical representation of the plan with progress for each stage.
For the command line it would be great to just dump the current status, which would provide a snapshot of the explain
analyze.

Now this is something that would really help testing a system, by
dynamically seeing the plans of queries which run too long. That
combined with the ability to see the values of bind parameters would be
a useful debug aid.
